cleavage
Back to Board
Identification - $100
Break mineral apart to see if it splits along
flat surfaces. What test is this?
Cleavage and Fracture
Back to Board

Density
Back to Board
Identification - $300
Observe surface of mineral. What test is
this?
Color
Back to Board
Identification - $400
a. Observe color of powder on unglazed tile.
b. Perform scratch test
What tests are these?
a. Streak
b. Hardness
Back to Board

Applications - $100
What is an advantage and a disadvantage
to using color to identify a mineral?
The color of a mineral is an easily observed
property. However, many minerals occur in
a variety of colors, so few minerals can be
identified based only on their color.
Back to Board
Applications - $200
About how many minerals have been
identified?
4,000
Back to Board
Applications - $300
What does a mineral’s streak tell you, and
how do you test for it?
A mineral’s streak tells the color of the
mineral when it is in powder form. The
streak test is helpful in telling apart two
minerals that are the same color. Even
though the minerals look alike, their streak
is often different. A mineral is tested for
streak by rubbing it against a piece of
unglazed tile, or a streak plate.

What is the hardest known mineral?
Diamond
Back to Board
Applications - $500
What is the difference between what mineral
properties tell us and what mineral tests tell
us? Explain.
Mineral properties tell us if something is a
mineral or not and mineral tests help us
identify minerals.
